Fegin调用时出现JSON parse error：can not deserialize instance of ...

本文主要是介绍Fegin调用时出现JSON parse error：can not deserialize instance of ...，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、问题

接口调用时提示json解析报错，如图
在这里插入图片描述

二、解决

通过排查发现Fegin调用时出现问题，Fegin调用的代码时这样写的：

employeeFeignClient.addRole(iamOrganizationId,employeeId,roleIds);

Fegin类是这样写的：

@PutMapping("/v1/{iam_organization_id}/organizations/employee/{employee_id}/role")
ResponseEntity<Integer> addRole(@PathVariable("iam_organization_id") Long iamOrganizationId,@PathVariable("employee_id") Long employeeId,@RequestBody List<Long> roleList) ;

json报错那可能在 @RequestBody这个参数这里出现问题，对比了调用服务的接口如下：

@Permission(level = ResourceLevel.ORGANIZATION)
@PutMapping("/{employee_id}/role")
@ApiOperation(value = "员工批量添加/修改角色")
public ResponseEntity<Integer> addRole(@PathVariable("iam_organization_id") Long iamOrganizationId,@PathVariable("employee_id") Long employeeId,@RequestBody List<Long> roleList) {return Optional.ofNullable(employeeService.addRole(iamOrganizationId, employeeId, roleList)).map(flag -> new ResponseEntity<>(flag, HttpStatus.OK)).orElseThrow(() -> new CommonException(ResponseCode.ERROR_ADD.getDesc()));
}
